I would very much like CBS to consider sending somebody to the TOS camera negative archives and look for the original VFX blue screen elements and restore the original VFX like they did for TNG-R (and I believe there'll be additional, unused and never before seen VFX shots). This would encourage me to buy TOS-R, again. (tell CBS!!!)
There are NO TOS VFX archives. That's why the effects had to be recreated using CGI. The effects were not archived back in the sixties after the show ended, they were tossed out.
